Great Big Story Have you ever wondered what happened to currency that gets damaged?

If you have a paper shredder in your home, you already have a pretty good idea. But that's just the start.

Great Big Story created a video to follow old bills through the process of their transformation..into plant food. It starts at the New Orleans branch of the Atlanta Federal Reserve Bank. Millions of dollars a day pass through the facility and are shredded before being composted.

Scroll on to see how the process works.

1/

The New Orleans branch of the Federal Reserve shreds $6 million in cash each day. They mainly shred bills that are dirty, taped, graffitied or otherwise unfit to be used as cash.

2/

The bills are shredded to a fine texture to make compost. The bills used to go to a landfill, but now they are recycled.

3/

The cash is transferred to a compost facility​, where it is mixed with other materials to make nutritious plant food.

After the compost is made, it is sold to local farmers, who use it to grow peppers, tomatoes and cucumbers.

"It is very fulfilling to be growing using a material that would otherwise go to waste." — Simond Menasche, founder and director of Grown On.
